.To all whom it may concern.-

Beit known that I, AMos DICKERMAN, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Process of and Mechanism for Cupping Paper Shells for Cartridges; and Ido declare the fol lowing to be afull, clear, and exact description of the same, reference being had to the accompanying drawings, which form a part ofv this specification. l f

My invention relates to an improved mechanismforcupping paper shells for cartridges,

the object being to secure the cups to the shells and to develop the heads of the cups at one and the same operation and without crimping the shells, whereby the expense of producing the cartridges is reduced, an article of uniform dimensions-is secured, and the maxi mum percentage of perfect pieces obtained.

With these ends in viewmy invention consists in reducing the cups of cartridges onto theshells thereof, and thus securing the cups tothe shells and developing the/heads of the cups at one and the saine operation.

My invention further consists in mechanism having certain details of construction and combinations of parts, as .will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in vertical longitudinal section of a machine embodyingmy invention, and showing the mechanism for running the cup-dial.- Fig'. 2 -is a similar view of the opposite side of anism are, the annular dies A, the pins B,

means for supporting the latter until the cups and shells have been properly assembled, and devices for automatically bringing the shells Fig. 5 is a detail view of` and cups together. The said dies A are each provided with acentral opening, including an enlarged portion, .1, located next to the l'ace of the die and adapted to receive an assembled cup and shell, a beveled portion, b,.lo cated next below the enlarged portion and adapted to reduce the cup onto the shell and develop` the head of the cup, and a cylindrical main portion, c, located below the beveled portion and. adapted to contain the shell and the reduced portions of the cup. rlhe said" dies'are located and secured by' set-screws C in cells D, formed in the'upper face of the shelldial E, which is mounted in a powerpress, F, of any approved construction and revolved by any suitable mechanism. The pins, on the other handI extend through the dies and to about the levclof the upper face' of the dial from a series 'of cells G, l'ornied in the lower face'of the saine, corresponding in position to the cells l) aforesaid, and connected with them by passages H, vcorresponding in diameter to the openingsof the dies. ln virtue of the described construction and arrangement 0f parts an annular space, l, of suflicient capacity to receive a K, extending into a eounterbore, L, formed in it and secured to a block, M, filling the lower end of the cell G ofthe pin and travel' ing upon thetbed N of the machine. For the purpose of insuring the proper assembling of the cups and shells before they are depressed into the dies, means are provided for supporting the pins -until such assembling is effected in their elevated .positions,in which their upper ends are about on a level with the upper face of thedial. ings, the means for the Vpurpose consist of a spring, O, interposed between the follower and the block of the guide-pin of each pin. It is apparent, however, that the springs may be replaced by other devices answering the same purpose.

For enabling the pins and the contentsof the lower cells to be removed for attention and repair, the bed of the machine is provided with an aperture, l?, with which the respective cells areregistered by revolving the dial,

go As shown in the drawand through which the said parts are Withdrawn by removing a sliding plate, Q, sunk into the bed of the machine.

The shells are supplied to the shell-dial by an attendant,who thrusts them upon the pins as the dial revolves, and when in the revolution ofthe dial the respective shells are brought under the punch R,'whieh is mounted in the cross-head S of the press, they are supplied with a cup from a carrier-block, T, mounted andv reciprocating in a hanger, U, provided with an arm, V, throngh which it is bolted to its upright rif of the press. Thev bolt-holes of the said arn'i are elongated, as will be observed by referenceto Fig. 2 of the drawings, for permitting the hanger and the mechanism associated `:Vith it to be vertically adj usted for adapting the machine to cup-shells vary ing in length. The said carrier-block is provided with an arm, Xhaving a pivotal finger, Y, which lis actuated in being closed by a spring, Z, secured to the said arm, and in being opened oy engagement with the same, for which purpose the finger is provided with an extension, A, and the said arm with a shoulder, B', as shown. The arm and finger are eut away to form the opening C', into which the cups are introduced from and by the revolving cupdial D', to which the cups are supplied by an attendant, and by which they are carried through a curved channel, E', formed in the under face of the hanger, and arranged to register with the opening C when the carrierblock is retracted and the ringer opened. The said dial is located beneath the hanger, in which it isjournaled by means of the hub E and the nut F, as shown, and actuated by the vertical shaft G, to which it is splined, and upon which it is vertically adjustable with the hanger. The said shaft, which is suspended from a bracket, H', secured tothe upright l' ofthe press, is actuated through bevel-gears J" and liand bandwheel Loir other equivalent means. The carrierblock is moved forward by means of a spring, M, attached to an adjustable arm, N, secured to the block and to a pin, O', projecting inwardly from the arm, V aforesaid. On the other hand, the block is retracted by means ofthe crosshead S, which is provided with a roller, P', and operates through a lever, Q', pivoted to an adjustable plate, It', bolted to the upright W aforesaid, the lower end of the lever being fiexibly connected with the block through an opening, S, formed therein. An adjustable support, located beneath the cup dial, is dcsigned to uphold the same and prevent in-.

jury to the machinein case of confiict between the punch and the carrier-block.

For the purpose of leveling the sheets preparatory to the application of the cups, the press is provided with a punch, U', which descends upon the shells and deprcsses them prior 'to their registration with the punch It, before referred to. After the said punch It has donc its work, the cupped shells are partiullytjected from the shell-dial, that they may be removed by the pick-ofi" V lent device. i i

The mechanism herein show-n for ejecting the shells consists of a springactuated pin, W', arranged to be impnged upon the blocks of the pins, a lever, X', and an adjustable rod, Y, all as shown in Fig.1 of the drawings. I would havel it understood, however,vthat the described means forleveling the shells and for ejecting them after being cupped constitutes no part of this invention, being shown simply for the purpose of presenting a completelyequipped machine.

With more particular reference now to the shells and cups, they are shown in the last three figures of the drawings. The shells Z" used in'my process are plain uncrimped cyl inders made in the usual manner, and having the wad A2 in position, while the cupsB2 are simplecylindrical figures, having one end closed and adapted to fit loosely over and rest upon the lends of the'shells.

In Fig. 5 the shell and cup are represented prior to beingv assembled, in Fig.` 4 after this operation has been affected, and in Fig. 6 after the cup has been reduced onto the shell, the head of the cup formed, and the edges of the or an equivashell crowded out into the open head of the cup. The head, it will be observed, is fully developed, but is yet to undergo a finishing operation in which its opposi te walls are drawn together and the edge of the shell pinched between them. k A

Having thus described the mechanism for carrying out my improved process, I will now proceed to more full y set forth the latter and to unfold the advantages attendant upon its use.

Shells and cups are supplied to their respective dials and the several parts of the machine timed or set to operate in harmony. The revolution of the shell-dial first brings the shells under the leveling-punch, by which they are depressed as required, and then, as they are carried toward the assembling and operating punch, the carrier-block advances with a cup until dually the cup and shell are exact-ly registered with the said punch, which descends and dislodges the cup, which settles down upon theshell. The punch, continuing its descent,'carries with it the cup and shell and forces the latter intogthe dial, the pi n with which the shell is engaged remaining stationary until the parts are properly assembled, as shown in Fig. flV of thedrawings. It is proper to note in this connection that, if not before, the parts will necessarily assume their proper positions as soon as the wad strikes the pin. After the parts have been assembled thecup and shell are forced by the punch into the die, where the cup is reduced onto theshell by: its simultaneous introduction with the same into the contracted part thereof. The described reduction of the cup develops its head, which' consists of so much of it as is forced no farther than' the flaring vportion of the die. During the last part of the opera- IOC) IIO

sequent thereupon are,avoided,as well as thel expense which the crimping entails., Again,

, the invariably correct assembling of the cups and shells prior to the securing of the former to the latter insures a uniformity in the product as to length not before attained. Furthermore, by developing the heads as described, instead of expanding the cups for forming the heads, headsgof uniform thickness and size are obtained, and the maximum of perfect cupped shells are secured..

lt is apparent that some changes may be made in the mechanism shown and described, and [would therefore have it understood that I hold myself at liberty to make such alterations as fairly fallwithin the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
